I understand that Trump supporters don't care about stuff like this because Trump supporters, generally, are immoral, unethical, fascists and authoritarians, and are also just bullies in general who think it's funny to push other people around, but it's still wrong.
And if I can't convince you of that, then maybe a more "powerful" authority can...
A tweet from Miami-Dade County Democratic Chairman Steve Simeonidis about a police officer who wore a pro-Trump mask at the polls is true.

That's a strawman. No one suggested the cop is going to shoot anyone. And then you're telling me and others to "get a grip" based on something no one never suggested.
He cannot express his political opinions while wearing his official uniform. It's wrong according to the policy of his dept. and it's wrong as a matter of general principle.
The reason? It's a coercive and abusive use of his authority as a police officer.
